If you rotate your proxy authentication credential, use the UpdateCustomKeyStore operation to provide the new credential to KMS.
        public let xksProxyAuthenticationCredential: XksProxyAuthenticationCredentialType?
        /// Indicates how KMS communicates with the external key store proxy. This parameter is required for custom key stores with a CustomKeyStoreType of EXTERNAL_KEY_STORE. If the external key store proxy uses a public endpoint, specify PUBLIC_ENDPOINT. If the external key store proxy uses a Amazon VPC endpoint service for communication with KMS, specify VPC_ENDPOINT_SERVICE. For help making this choice, see Choosing a connectivity option in the Key Management Service Developer Guide. An Amazon VPC endpoint service keeps your communication with KMS in a private address space entirely within Amazon Web Services, but it requires more configuration, including establishing a Amazon VPC with multiple subnets, a VPC endpoint service, a network load balancer, and a verified private DNS name. A public endpoint is simpler to set up, but it might be slower and might not fulfill your security requirements. You might consider testing with a public endpoint, and then establishing a VPC endpoint service for production tasks. Note that this choice does not determine the location of the external key store proxy. Even if you choose a VPC endpoint service, the proxy can be hosted within the VPC or outside of Amazon Web Services such as in your corporate data center.
        public let xksProxyConnectivity: XksProxyConnectivityType?

This parameter is required for custom key stores with a CustomKeyStoreType of EXTERNAL_KEY_STORE. The protocol must be HTTPS. KMS communicates on port 443. Do not specify the port in the XksProxyUriEndpoint value. For external key stores with XksProxyConnectivity value of VPC_ENDPOINT_SERVICE, specify https:// followed by the private DNS name of the VPC endpoint service. For external key stores with PUBLIC_ENDPOINT connectivity, this endpoint must be reachable before you create the custom key store. KMS connects to the external key store proxy while creating the custom key store. For external key stores with VPC_ENDPOINT_SERVICE connectivity, KMS connects when you call the ConnectCustomKeyStore operation. The value of this parameter must begin with https://. The remainder can contain upper and lower case letters (A-Z and a-z), numbers (0-9), dots (.), and hyphens (-). Additional slashes (/ and \) are not permitted.  Uniqueness requirements:     The combined XksProxyUriEndpoint and XksProxyUriPath values must be unique in the Amazon Web Services account and Region.   An external key store with PUBLIC_ENDPOINT connectivity cannot use the same XksProxyUriEndpoint value as an external key store with VPC_ENDPOINT_SERVICE connectivity in this Amazon Web Services Region.   Each external key store with VPC_ENDPOINT_SERVICE connectivity must have its own private DNS name. The XksProxyUriEndpoint value for external key stores with VPC_ENDPOINT_SERVICE connectivity (private DNS name) must be unique in the Amazon Web Services account and Region.

This parameter is required for all custom key stores with a CustomKeyStoreType of EXTERNAL_KEY_STORE. The value must start with / and must end with /kms/xks/v1 where v1 represents the version of the KMS external key store proxy API. This path can include an optional prefix between the required elements such as /prefix/kms/xks/v1.

The encryption context grant constraints are supported only on grant operations that include an EncryptionContext parameter, such as cryptographic operations on symmetric encryption KMS keys. Grants with grant constraints can include the DescribeKey and RetireGrant operations, but the constraint doesn't apply to these operations.

Each constraint value can include up to 8 encryption context pairs. The encryption context value in each constraint cannot exceed 384 characters.

Tagging or untagging a KMS key can allow or deny permission to the KMS key. For details, see ABAC for KMS in the Key Management Service Developer Guide.  To use this parameter, you must have kms:TagResource permission in an IAM policy. Each tag consists of a tag key and a tag value. Both the tag key and the tag value are required, but the tag value can be an empty (null) string. You cannot have more than one tag on a KMS key with the same tag key. If you specify an existing tag key with a different tag value, KMS replaces the current tag value with the specified one. When you add tags to an Amazon Web Services resource, Amazon Web Services generates a cost allocation report with usage and costs aggregated by tags. Tags can also be used to control access to a KMS key. For details, see Tags in KMS.

        /// Identifies the external key that serves as key material for the KMS key in an external key store. Specify the ID that the external key store proxy uses to refer to the external key. For help, see the documentation for your external key store proxy. This parameter is required for a KMS key with an Origin value of EXTERNAL_KEY_STORE. It is not valid for KMS keys with any other Origin value. The external key must be an existing 256-bit AES symmetric encryption key hosted outside of Amazon Web Services in an external key manager associated with the external key store specified by the CustomKeyStoreId parameter. This key must be enabled and configured to perform encryption and decryption. Each KMS key in an external key store must use a different external key. For details, see Requirements for a KMS key in an external key store in the Key Management Service Developer Guide. Each KMS key in an external key store is associated two backing keys. One is key material that KMS generates. The other is the external key specified by this parameter. When you use the KMS key in an external key store to encrypt data, the encryption operation is performed first by KMS using the KMS key material, and then by the external key manager using the specified external key, a process known as double encryption. For details, see Double encryption in the Key Management Service Developer Guide.

Many failures can be resolved by updating the properties of the custom key store. To update a custom key store, disconnect it (DisconnectCustomKeyStore), correct the errors (UpdateCustomKeyStore), and try to connect again (ConnectCustomKeyStore). For additional help resolving these errors, see How to Fix a Connection Failure in Key Management Service Developer Guide.  All custom key stores:     INTERNAL_ERROR — KMS could not complete the request due to an internal error. Retry the request. For ConnectCustomKeyStore requests, disconnect the custom key store before trying to connect again.    NETWORK_ERRORS — Network errors are preventing KMS from connecting the custom key store to its backing key store.    CloudHSM key stores:     CLUSTER_NOT_FOUND — KMS cannot find the CloudHSM cluster with the specified cluster ID.    INSUFFICIENT_CLOUDHSM_HSMS — The associated CloudHSM cluster does not contain any active HSMs. To connect a custom key store to its CloudHSM cluster, the cluster must contain at least one active HSM.    INSUFFICIENT_FREE_ADDRESSES_IN_SUBNET — At least one private subnet associated with the CloudHSM cluster doesn't have any available IP addresses. A CloudHSM key store connection requires one free IP address in each of the associated private subnets, although two are preferable. For details, see How to Fix a Connection Failure in the Key Management Service Developer Guide.    INVALID_CREDENTIALS — The KeyStorePassword for the custom key store doesn't match the current password of the kmsuser crypto user in the CloudHSM cluster. Before you can connect your custom key store to its CloudHSM cluster, you must change the kmsuser account password and update the KeyStorePassword value for the custom key store.    SUBNET_NOT_FOUND — A subnet in the CloudHSM cluster configuration was deleted. If KMS cannot find all of the subnets in the cluster configuration, attempts to connect the custom key store to the CloudHSM cluster fail. To fix this error, create a cluster from a recent backup and associate it with your custom key store. (This process creates a new cluster configuration with a VPC and private subnets.) For details, see How to Fix a Connection Failure in the Key Management Service Developer Guide.    USER_LOCKED_OUT — The kmsuser CU account is locked out of the associated CloudHSM cluster due to too many failed password attempts. Before you can connect your custom key store to its CloudHSM cluster, you must change the kmsuser account password and update the key store password value for the custom key store.    USER_LOGGED_IN — The kmsuser CU account is logged into the associated CloudHSM cluster. This prevents KMS from rotating the kmsuser account password and logging into the cluster. Before you can connect your custom key store to its CloudHSM cluster, you must log the kmsuser CU out of the cluster. If you changed the kmsuser password to log into the cluster, you must also and update the key store password value for the custom key store. For help, see How to Log Out and Reconnect in the Key Management Service Developer Guide.    USER_NOT_FOUND — KMS cannot find a kmsuser CU account in the associated CloudHSM cluster. Before you can connect your custom key store to its CloudHSM cluster, you must create a kmsuser CU account in the cluster, and then update the key store password value for the custom key store.    External key stores:     INVALID_CREDENTIALS — One or both of the XksProxyAuthenticationCredential values is not valid on the specified external key store proxy.    XKS_PROXY_ACCESS_DENIED — KMS requests are denied access to the external key store proxy. If the external key store proxy has authorization rules, verify that they permit KMS to communicate with the proxy on your behalf.    XKS_PROXY_INVALID_CONFIGURATION — A configuration error is preventing the external key store from connecting to its proxy. Verify the value of the XksProxyUriPath.    XKS_PROXY_INVALID_RESPONSE — KMS cannot interpret the response from the external key store proxy. If you see this connection error code repeatedly, notify your external key store proxy vendor.    XKS_PROXY_INVALID_TLS_CONFIGURATION — KMS cannot connect to the external key store proxy because the TLS configuration is invalid. Verify that the XKS proxy supports TLS 1.2 or 1.3. Also, verify that the TLS certificate is not expired, and that it matches the hostname in the XksProxyUriEndpoint value, and that it is signed by a certificate authority included in the Trusted Certificate Authorities list.    XKS_PROXY_NOT_REACHABLE — KMS can't communicate with your external key store proxy. Verify that the XksProxyUriEndpoint and XksProxyUriPath are correct. Use the tools for your external key store proxy to verify that the proxy is active and available on its network. Also, verify that your external key manager instances are operating properly. Connection attempts fail with this connection error code if the proxy reports that all external key manager instances are unavailable.    XKS_PROXY_TIMED_OUT — KMS can connect to the external key store proxy, but the proxy does not respond to KMS in the time allotted. If you see this connection error code repeatedly, notify your external key store proxy vendor.    XKS_VPC_ENDPOINT_SERVICE_INVALID_CONFIGURATION — The Amazon VPC endpoint service configuration doesn't conform to the requirements for an KMS external key store.   The VPC endpoint service must be an endpoint service for interface endpoints in the caller's Amazon Web Services account.   It must have a network load balancer (NLB) connected to at least two subnets, each in a different Availability Zone.   The Allow principals list must include
        /// 	         the KMS service principal for the Region, cks.kms..amazonaws.com,
        /// 	         such as cks.kms.us-east-1.amazonaws.com.   It must not require acceptance of connection requests.   It must have a private DNS name. The private DNS name for an external key store with VPC_ENDPOINT_SERVICE connectivity

        /// 	         verified.   The TLS certificate specifies the private DNS hostname at which the endpoint is reachable.      XKS_VPC_ENDPOINT_SERVICE_NOT_FOUND — KMS can't find the VPC endpoint service that it uses to communicate with the external key store proxy. Verify that the XksProxyVpcEndpointServiceName is correct and the KMS service principal has service consumer permissions on the Amazon VPC endpoint service.

For an external key store, the ConnectionState indicates whether it is connected to the external key store proxy that communicates with your external key manager. You can create and use KMS keys in your custom key stores only when its ConnectionState is CONNECTED. The ConnectionState value is DISCONNECTED only if the key store has never been connected or you use the DisconnectCustomKeyStore operation to disconnect it. If the value is CONNECTED but you are having trouble using the custom key store, make sure that the backing key store is reachable and active. For an CloudHSM key store, verify that its associated CloudHSM cluster is active and contains at least one active HSM. For an external key store, verify that the external key store proxy and external key manager are connected and enabled. A value of FAILED indicates that an attempt to connect was unsuccessful.

For example:   Key ID: 1234abcd-12ab-34cd-56ef-1234567890ab    Key ARN: arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab    Alias name: alias/ExampleAlias    Alias ARN: arn:aws:kms:us-east-2:111122223333:alias/ExampleAlias    To get the key ID and key ARN for a KMS key, use ListKeys or DescribeKey. To get the alias name and alias ARN, use ListAliases.

Use RAW for unhashed messages; use DIGEST for message digests, which are already hashed; use EXTERNAL_MU for 64-byte representative μ used in ML-DSA signing as defined in NIST FIPS 204 Section 6.2. When the value of MessageType is RAW, KMS uses the standard signing algorithm, which begins with a hash function. When the value is DIGEST, KMS skips the hashing step in the signing algorithm. When the value is EXTERNAL_MU KMS skips the concatenated hashing of the public key hash and the message done in the ML-DSA signing algorithm.  Use the DIGEST or EXTERNAL_MU value only when the value of the Message parameter is a message digest. If you use the DIGEST value with an unhashed message, the security of the signing operation can be compromised.  When the value of MessageType is DIGEST, the length of the Message value must match the length of hashed messages for the specified signing algorithm. When the value of MessageType is EXTERNAL_MU the length of the Message value must be 64 bytes. You can submit a message digest and omit the MessageType or specify RAW so the digest is hashed again while signing. However, this can cause verification failures when verifying with a system that assumes a single hash. The hashing algorithm that Sign uses is based on the SigningAlgorithm value.   Signing algorithms that end in SHA_256 use the SHA_256 hashing algorithm.   Signing algorithms that end in SHA_384 use the SHA_384 hashing algorithm.   Signing algorithms that end in SHA_512 use the SHA_512 hashing algorithm.   Signing algorithms that end in SHAKE_256 use the SHAKE_256 hashing algorithm.   SM2DSA uses the SM3 hashing algorithm.

Use RAW for unhashed messages; use DIGEST for message digests, which are already hashed; use EXTERNAL_MU for 64-byte representative μ used in ML-DSA signing as defined in NIST FIPS 204 Section 6.2. When the value of MessageType is RAW, KMS uses the standard signing algorithm, which begins with a hash function. When the value is DIGEST, KMS skips the hashing step in the signing algorithm. When the value is EXTERNAL_MU KMS skips the concatenated hashing of the public key hash and the message done in the ML-DSA signing algorithm.  Use the DIGEST or EXTERNAL_MU value only when the value of the Message parameter is a message digest. If you use the DIGEST value with an unhashed message, the security of the signing operation can be compromised.  When the value of MessageType is DIGEST, the length of the Message value must match the length of hashed messages for the specified signing algorithm. When the value of MessageType is EXTERNAL_MU the length of the Message value must be 64 bytes. You can submit a message digest and omit the MessageType or specify RAW so the digest is hashed again while signing. However, if the signed message is hashed once while signing, but twice while verifying, verification fails, even when the message hasn't changed. The hashing algorithm that Verify uses is based on the SigningAlgorithm value.   Signing algorithms that end in SHA_256 use the SHA_256 hashing algorithm.   Signing algorithms that end in SHA_384 use the SHA_384 hashing algorithm.   Signing algorithms that end in SHA_512 use the SHA_512 hashing algorithm.   Signing algorithms that end in SHAKE_256 use the SHAKE_256 hashing algorithm.   SM2DSA uses the SM3 hashing algorithm. For details, see Offline verification with SM2 key pairs.
